System and method for multicolumn sorting in a single column |
摘要 |
A system for multicolumn ordering includes a processor and a data store. The data store stores a table including a plurality of category and data columns. The processor applies key prefixes to column data values of a plurality of the data columns to form and store in the data store a set of prefixed data values. The processor then orders the set of prefixed data values in a first compound column and one or more category columns in a second compound column and responsive to the first and second compound columns selects and stores a subset for further processing.
